This book examines a topic which is an indispensable part of any production line in the wood industry: the extraction, separation, handling of dust and chips, ensuring clean air in the workrooms, and avoiding health, fire and explosion risks. All scientific backgrounds of these problems are not fully known today, and efforts should be made to fill this gap. The work contains significant new derivations and calculation methods and experimental results to support design and evaluation methods such as particle size distributions depending on wood species and machining, terminal velocity of small wood particles, aerodynamics of suction hoods, a detailed analysis of particle separation in cyclones, selection and evaluation of separation efficiency for appropriate filter selection, energy consumption and transportation efficiency of pneumatic conveying, a comprehensive theory of transport ventilators. Several new details of dust explosion are also included. The calculation methods, practical solutions and recommendations are supported by physically well-established explanations providing long-lasting knowledge.

Exposure to wood dust presents a health hazard to woodworkers and the need for dust control has received coverage in the woodworking press. This guide shows how to choose appropriate equipment; how to use it and describes the tools and strategies needed to ensure a healthier working environment.

In the fifteen years since the publication of Occupational Ergonomics: Theory and Applications significant advances have been made in this field. These advances include understanding the impact of ageing and obesity on workplace, the role of ergonomics in promoting healthy workplaces and healthy life styles, the role of ergonomic science in th

The Art Of Lutherie offers a glimpse into the mind and craft of luthier Tom Bills, whom many consider to be one of the most talented luthiers today. In this beautifully written and enjoyable read, Tom elegantly and clearly shares his best- kept secrets and methods of custom guitar making - those which make his guitars favorites among top collectors and players. Tom's unique approach to The Art Of Lutherie will empower and inspire you to create more than just a guitar, but a truly unique work of art. The information that is generously shared within this insightful and timeless work is both practical and applicable. It contains the same hard-won wisdom that only comes from years of experience and experimentation that Tom uses in creating his inspiring instruments. Over the years, he has producedinstruments considered to be some of the bestsounding guitars ever made. Learning the steps of how to build a guitar is important, but understanding whymaster luthiers take those steps and make those decisions can empower you to make your own educated choices. This will allow you to create unique guitars, and the world needs your art, your guitars - your important contribution. The Art Of Lutherie, a truly unique and inspiring guide, can prepare you to reach new heights when designing and creating unique guitars. It is not often I heap such lavish praise on people; however, Tom is in this case more than deserving: I know of no other luthier whose work I respect more. Tom knows his craft inside and out; he pours his soul into every guitar he makes; heuses cutting-edge science to guide his work, and it shows...as head of Artist Relations and Product Development at Mel Bay, it gives me great pleasure topublish Tom's work, which will no doubt take the art of lutherie to a new level. I hope you'll spend some time soaking in this book - it will certainly augmentyour musicality - Collin Bay. Includes access to online video

Throughout the mining and processing of minerals, the mined ore undergoes a number of crushing, grinding, cleaning, drying, and product sizing operations as it is processed into a marketable commodity. These operations are highly mechanized, and both individually and collectively these processes can generate large amounts of dust. If control technologies are inadequate, hazardous levels of respirable dust may be liberated into the work environment, potentially exposing workers. Accordingly, federal regulations are in place to limit the respirable dust exposure of mine workers. Engineering controls are implemented in mining operations in an effort to reduce dust generation and limit worker exposure.

This fourth edition provides guidance on why respiratory protective equipment (RPE) should be used, what the law says and how to select RPE that is adequate and suitable. It also includes a useful dos and don'ts list for the management and supervision of RPE use.The guidance is aimed principally at employers and the self-employed who wear, or are responsible for workers who wear, RPE. It will also be useful for health and safety specialists, manufacturers and suppliers of RPE.It has been prepared in consultation with industry and updates the 2005 edition

Compelling photographic essays from photographer Eilon Paz are paired with in-depth and insightful interviews to illustrate what motivates these collectors to keep digging for more records. The reader gets an up close and personal look at a variety of well-known vinyl champions, including Gilles Peterson and King Britt, as well as a glimpse into the collections of known and unknown DJs, producers, record dealers, and everyday enthusiasts. Driven by his love for vinyl records, Paz takes us on a five-year journey unearthing the very soul of the vinyl community.

Unfortunately, dust explosions are common and costly in a wide array of industries such as petrochemical, food, paper and pharmaceutical. It is imperative that practical and theoretical knowledge of the origin, development, prevention and mitigation of dust explosions is imparted to the responsible safety manager. The material in this book offers an up to date evaluation of prevalent activities, testing methods, design measures and safe operating techniques. Also provided is a detailed and comprehensive critique of all the significant phases relating to the hazard and control of a dust explosion. An invaluable reference work for industry, safety consultants and students. - A completely new chapter on design of electrical equipment to be used in areas containing combustible/explosible dust - A substantially extended and re-organized final review chapter, containing nearly 400 new literature references from the years 1997-2002 - Extensive cross-referencing from the original chapters 1-7 to the corresponding sections of the expanded review chapter
